Generation

Stirling numbers count two fundamental ways of partitioning sets. **Stirling numbers of the second kind** S(n,k) tell you how many ways you can divide n distinct objects into k non-empty groups (where the groups themselves are unlabeled) — for example, S(4,2) = 7 counts ways to split 4 people into 2 unlabeled teams. **Stirling numbers of the first kind** s(n,k) count permutations of n objects that break into exactly k cycles — they're closely connected to converting between falling factorials and ordinary powers. Both appear throughout combinatorics, with the second kind being especially important for counting onto functions and set partitions.
